According to this configuration, the exterior member and the first pathregulating member can be pressed against the cover portion by the fillerintroduced into the space between the exterior member and the coverportion. Also, due to the filler being provided in the insertion openingof the first path regulating member, rotation of the first pathregulating member in the circumferential direction can be suppressed bythe filler. Moreover, due to the filler being formed in the insertionopening of the first path regulating member, the cover portion can havea smaller size in the diameter direction than in the case of aconfiguration in which the filler is provided so as to be in contactwith the outer circumferential surface of the first path regulatingmember.

[3] It is preferable that the through hole faces the insertion openingin a diameter direction of the cover portion.

According to this configuration, the filler can be favorably introducedinto the insertion opening.

According to this configuration, the cover portion is provided at alengthwise end portion of the second path regulating member, and coversthe outer circumferential surface of a lengthwise end portion of thefirst path regulating member. For this reason, the first path regulatingmember and the second path regulating member are coupled in the lengthdirection. Accordingly, the path of the exterior member is regulatedwith continuity by the first path regulating member and the second pathregulating member.

As shown in FIGS. 3 and 4 , the electric wire member 20 includes one ormore electric wires 21 (two in the present embodiment) and a braidedmember 25 that surrounds all of the electric wires 21, for example.

Each of the electric wires 21 is a coated electric wire that includes aconductive core wire 22 and an insulating covering 23 that surrounds thecore wire 22 and has insulating properties. Each electric wire 21 is ahigh-voltage electric wire that can conduct a high voltage and a largecurrent, for example. Each electric wire 21 may be a non-shieldedelectric wire that does not have an electromagnetic shield structure, ora shielded electric wire that has an electromagnetic shield structure,for example. Each electric wire 21 in the present embodiment is anon-shielded electric wire.

The core wire 22 can be a stranded wire that is constituted by aplurality of metal strands twisted together, a single core wire that isconstituted by a single conductor, or the like. The single core wire canbe a columnar conductor that is constituted by one columnar metal rodwith a solid internal structure, a tubular conductor with a hollowinternal structure, or the like. The core wire 22 may be any combinationof a stranded wire, a columnar conductor, and a tubular conductor. Thecore wire 22 can be made of a metal material such as a copper-basedmaterial or an aluminum-based material, for example.

The insulating covering 23 covers an entire circumferential range of theouter circumferential surface of the core wire 22, for example. Theinsulating covering 23 is constituted by a resin material that hasinsulating properties, for example.

The cross-sectional shape of each electric wire 21 cut along a planeorthogonal to the length direction of the electric wire 21, that is tosay the transverse cross-sectional shape of each electric wire 21, canbe any shape. The transverse cross-sectional shape of each electric wire21 may be a circular shape, a semicircular shape, a polygonal shape, asquare shape, or a flattened shape, for example. The transversecross-sectional shape of each electric wire 21 in the present embodimentis a circular shape.

The braided member 25 has a tubular shape that surrounds the outercircumferential surfaces of all of the electric wires 21, for example.The braided member 25 can be a braided wire in which a plurality ofmetal strands are braided together, or a braided wire in which acombination of metal strands and resin strands are braided together, forexample. The metal strands can be formed using a metal material such asa copper-based material or an aluminum-based material, for example.Although not shown in the drawings, the two lengthwise end portions ofthe braided member 25 are grounded at the connectors C1 and C2 (see FIG.1 ), for example.

Configuration of Exterior Member 30

The exterior member 30 has a tubular shape surrounding the entirecircumferential range of the outer circumferential surface of theelectric wire member 20. The exterior member 30 in the presentembodiment has a cylindrical shape. The exterior member 30 is providedwith a circumferential wall that is formed so as to be continuous overthe entire circumferential range of the outer circumferential surface ofthe exterior member 30, for example. The exterior member 30 is sealedover the entire circumferential range of the outer circumferentialsurface of the exterior member 30, for example. The exterior member 30has a function of protecting the electric wire member 20 from flyingobjects and water droplets, for example.

The exterior member 30 has flexibility and is easily bendable, forexample. The flexible exterior member 30 can be a resin corrugated tubeor a rubber waterproof cover, for example. The exterior member 30 of thepresent embodiment is a corrugated tube made of resin having a bellowsshape whose diameter repeatedly increases and decreases in the lengthdirection of the exterior member 30. In other words, the exterior member30 of the present embodiment has a bellows structure in whichlarge-diameter portions 31 and small-diameter portions 32, which aresmaller in diameter than the large-diameter portions 31, arealternatingly connected along the length direction of the exteriormember 30. The large-diameter portions 31 and the small-diameterportions 32 each have an annular shape that extends one time around thecircumference of the exterior member 30, for example. The exteriormember 30 can be made of a synthetic resin such as polyolefin,polyamide, polyester, or ABS resin, for example. Note that in FIG. 2 ,the exterior member 30 is illustrated in a simplified manner for thesake of simplification of the drawing.

Configuration of First Path Regulating Member 40 and Second PathRegulating Member 50

As shown in FIGS. 2 and 3 , the first path regulating member 40 and thesecond path regulating member 50 each hold the exterior member 30. Thefirst path regulating member 40 and the second path regulating member 50are each harder than the exterior member 30, for example. The first pathregulating member 40 and the second path regulating member 50 each havea hardness according to which, compared with the exterior member 30,they less easily bend in a direction orthogonal to the length directionof the wire harness body 11. As a result, the first path regulatingmember 40 and the second path regulating member 50 each regulate thepath of the wire harness body 11. For example, the first path regulatingmember 40 and the second path regulating member 50 each assist theexterior member 30 such that the wire harness body 11 does not deviatefrom the desired path by bending due to its own weight or the like.

As shown in FIG. 2 , the first path regulating member 40 is providedalong a portion of the wire harness body 11 with respect to the lengthdirection. For example, the first path regulating member 40 is attachedto the outer circumferential surface of the exterior member 30 along astraight portion 11A, which is a portion extending in a straight linealong the path of the wire harness body 11. The first path regulatingmember 40 regulates the path of the wire harness body 11 in the straightportion 11A. Here, the straight portion 11A is a portion in which thepath of the wire harness body 11 extends straight in one direction. Notethat one or more first path regulating members 40 are provided dependingon the path of the wire harness body 11.

The second path regulating member 50 is provided along a portion of thewire harness body 11 with respect to the length direction. For example,the second path regulating member 50 is attached to the outercircumferential surface of the exterior member 30 along a bent portion11B, which is a portion that bends along the path of the wire harnessbody 11. The second path regulating member 50 regulates the path of thewire harness body 11 in the bent portion 11B. Here, the bent portion 11Bis a portion that bends such that the path of the wire harness body 11deviates from a straight line. Note that one or more second pathregulating members 50 may be provided depending on the path of the wireharness body 11.

Configuration of First Path Regulating Member 40

As shown in FIGS. 2 and 4 , the first path regulating member 40 coverspart of the outer circumferential surface of the exterior member 30 inthe circumferential direction of the exterior member 30. The first pathregulating member 40 has a shape that covers the outer circumferentialsurface of the exterior member 30 in a portion of the exterior member 30in the circumferential direction. The transverse cross-sectional shapeof the first path regulating member 40 is C-shaped overall. The firstpath regulating member 40 covers a range larger than half of the outercircumferential surface of the exterior member 30, for example.Specifically, the first path regulating member 40 covers a range of theouter circumferential surface of the exterior member 30 that is largerthan half of the entire circumference of the exterior member 30 in thecircumferential direction.

As shown in FIG. 2 , the first path regulating member 40 extends alongthe length direction of the exterior member 30 in the straight portion11A. The first path regulating member 40 is formed with a shapeextending in a straight line in one direction, for example. Thetransverse cross-sectional shape of the first path regulating member 40is uniform over the entire length of the first path regulating member 40in the length direction, for example.

The first path regulating member 40 is made of a metal or a resin, forexample. The first path regulating member 40 of the present embodimentis made of a resin. A synthetic resin such as polypropylene, polyamide,or polyacetal can be used as the material of the first path regulatingmember 40, for example. The first path regulating member 40 can bemanufactured through a known manufacturing method such as extrusionmolding or injection molding. In the present embodiment, the first pathregulating member 40 is an extrusion molded article manufactured byextrusion molding. For this reason, the first path regulating member 40can be easily manufactured by using an extrusion molder that extrudesthe raw material of the first path regulating member 40 in the lengthdirection. Also, a single extrusion molder can be used to manufacture aplurality of types of first path regulating members 40 that havedifferent dimensions in the length direction. For example, by cuttingthe base material of the first path regulating member 40 formed by asingle extrusion molder to an appropriate length using a cuttingmachine, a plurality of types of first path regulating members 40 havingdifferent dimensions in the length direction can be manufactured.

As shown in FIGS. 3 and 4 , the first path regulating member 40 has aninsertion opening 40X that is open in a direction orthogonal to thelength direction of the first path regulating member 40. The insertionopening 40X extends over the entirety of the first path regulatingmember 40 in the length direction. The first path regulating member 40includes a first end portion 41 and a second end portion 42 that are thetwo end portions of the first path regulating member 40 in thecircumferential direction and form the insertion opening 40X. The firstpath regulating member 40 includes a connecting portion 43 that connectsthe first end portion 41 and the second end portion 42. In other words,the first path regulating member 40 includes the connecting portion 43formed so as to cover a portion of the exterior member 30 in thecircumferential direction, the first end portion 41 and the second endportion 41 provided at the two end portions of the connecting portion43, and the insertion opening 40X formed by the first end portion 41 andthe second end portion 42.

The connecting portion 43 constitutes a main portion of the first pathregulating member 40. The thickness of the connecting portion 43 in thediameter direction is uniform along the circumferential direction of thefirst path regulating member 40, for example. The transversecross-sectional shape of the connecting portion 43 is a shape thatextends along the outer surface of the exterior member 30, for example.The transverse cross-sectional shape of the first end portion 41, thesecond end portion 42, and the connecting portion 43 is an arc shape,for example.

The first end portion 41 and the second end portion 42 are provided onopposite sides of the first path regulating member 40 in thecircumferential direction. The first end portion 41 and the second endportion 42 are separated from each other in the circumferentialdirection of the first path regulating member 40 with the insertionopening 40X interposed therebetween. In other words, the gap between thefirst end portion 41 and the second end portion 42 in thecircumferential direction of the first path regulating member 40 isconfigured as the insertion opening 40X. In this way, the first pathregulating member 40 is C-shaped and has the insertion opening 40X in aportion of the first path regulating member 40 in the circumferentialdirection.

The transverse cross-sectional shape of the leading ends of the firstend portion 41 and the second end portion 42 is a curved shape. Thetransverse cross-sectional shape of the leading ends of the first endportion 41 and the second end portion 42 of the present embodiment is anarc shape.

The first path regulating member 40 includes a protruding portion 45that protrudes from the inner surface of the first end portion 41 and aprotruding portion 46 that protrudes from the inner surface of thesecond end portion 42. The protruding portions 45 and 46 protrude towardthe exterior member 30 that has been inserted into the first pathregulating member 40, and come into contact with the outer surface ofthe exterior member 30. The protruding portions 45 and 46 come intocontact with the outer surfaces of the large-diameter portions 31 of theexterior member 30. The protruding portion 45 protrudes from the innersurface of the leading end of the first end portion 41, for example. Theprotruding portion 46 protrudes from the inner surface of the leadingend of the second end portion 42, for example. The transversecross-sectional shape of the protruding portions 45 and 46 is a curvedshape, for example. The transverse cross-sectional shape of theprotruding portions 45 and 46 of the present embodiment is an arc shape.The protruding portions 45 and 46 extend in the length direction of thefirst path regulating member 40. The protruding portions 45 and 46extend over the entirety of the first path regulating member 40 in thelength direction, for example.

The protruding portions 45 and 46 press the exterior member 30 fromoutside of the exterior member 30. The exterior member 30 is elasticallysandwiched between the protruding portion 45, the protruding portion 46,and the connecting portion 43. Accordingly, the coupling of the firstpath regulating member 40 to the exterior member 30 is strengthened.

As shown in FIG. 4 , the opening width of the insertion opening 40X,that is to say the shortest distance between the first end portion 41and the second end portion 42, is smaller than the outer diameter of theexterior member 30. The opening width of the insertion opening 40Xincreases as the first path regulating member 40 elastically deforms.For example, the opening width of the insertion opening 40X increasesdue to insertion of the exterior member 30 into the insertion opening40X in a direction orthogonal to the length direction of the first pathregulating member 40. When the exterior member 30 is inserted into thefirst path regulating member 40, the first path regulating member 40undergoes elastic restoration to return to the original shape.Accordingly, the first path regulating member 40 is attached to theouter circumferential surface of the exterior member 30 due to theopening width of the insertion opening 40X being smaller than the outerdiameter of the exterior member 30.

Configuration of Second Path Regulating Member 50

As shown in FIG. 2 , the second path regulating member 50 is attached tothe outer circumferential surface of the exterior member 30 in the bentportion 11B. The second path regulating member 50 extends along thelength direction of the exterior member 30 in the bent portion 11B. Thesecond path regulating member 50 is bent along the shape of the bentportion 11B, for example.

The second path regulating member 50 is made of a metal or a resin, forexample. The second path regulating member 50 of the present embodimentis made of a resin. A synthetic resin such as polypropylene, polyamide,or polyacetal can be used as the material of the second path regulatingmember 50, for example. The second path regulating member 50 can bemanufactured by a well-known manufacturing method such as injectionmolding.

As shown in FIGS. 2, 3, and 4 , the second path regulating member 50includes a body portion 51 (body) and a cover portion 52 (cover) thatcovers a lengthwise end portion of the first path regulating member 40.

The body portion 51 is formed in an elongated shape extending along thelength direction of the exterior member 30 in the bent portion 11B, forexample. The body portion 51 extends along the path of the bent portion11B, for example. In other words, the body portion 51 has a bent shapethat bends along the shape of the bent portion 11B. The body portion 51covers a portion of the outer circumferential surface of the exteriormember 30 in the circumferential direction of the exterior member 30.The body portion 51 covers a range of approximately half of the exteriormember 30 in the circumferential direction, for example. For example,the body portion 51 covers a range of approximately 180° of the exteriormember 30 in the circumferential direction. The body portion 51 has asubstantially semi-cylindrical shape, for example.

The cover portion 52 is provided at one lengthwise end portion of thebody portion 51. The cover portion 52 includes a receiving portion 53(receiver) that is integrated with the one lengthwise end portion of thebody portion 51, and a lid portion 54 (lid) that covers the receivingportion 53.

The receiving portion 53 covers a portion of the outer circumferentialsurface of the first path regulating member 40 in the circumferentialdirection of the first path regulating member 40. The receiving portion53 covers a portion of one lengthwise end portion of the first pathregulating member 40 in the circumferential direction. The receivingportion 53 has a shape that partially covers the outer circumferentialsurface of the first path regulating member 40 in the circumferentialdirection of the first path regulating member 40. The transversecross-sectional shape of the receiving portion 53 is a semi-cylindricalshape as a whole. The receiving portion 53 has a semi-cylindrical shapewith a diameter larger than that of the body portion 51, for example.The receiving portion 53 covers half of the first path regulating member40 in the circumferential direction, for example.

The lid portion 54 and the receiving portion 53 together cover theentire circumferential range of the end portion of the first pathregulating member 40. Specifically, the lid portion 54 and the receivingportion 53 together cover the entirety of the outer circumferentialsurface of the end portion of the first path regulating member 40 in thecircumferential direction. The lid portion 54 of the present embodimentcovers a portion of the outer circumferential surface of the first pathregulating member 40 and a portion of the outer circumferential surfaceof the exterior member 30 exposed from the insertion opening 40X.

The transverse cross-sectional shape of the lid portion 54 is asemi-cylindrical shape as a whole. The lid portion 54 has asemi-cylindrical shape with the same diameter as the receiving portion53. The lid portion 54 covers a range of half of the outercircumferential surface of the first path regulating member 40 in thecircumferential direction, which is a range of the outer circumferentialsurface of the first path regulating member 40 along the circumferentialdirection not covered by the receiving portion 53.

The lid portion 54 is a member that is separate from the receivingportion 53, for example. The receiving portion 53 includes firstcoupling portions 55. The first coupling portions 55 are respectivelyprovided at the two end portions of the receiving portion 53 in thecircumferential direction. The first coupling portions 55 protrudeoutward in the diameter direction from the two end portions of thereceiving portion 53 in the circumferential direction.

The lid portion 54 includes second coupling portions 56. The secondcoupling portions 56 are respectively provided at the two end portionsof the lid portion 54 in the circumferential direction. The secondcoupling portions 56 each include a groove 57 for insertion of thecorresponding first coupling portion 55. The grooves 57 extend along thelength direction of the second path regulating member 50. The secondcoupling portions 56 can be attached to the first coupling portions 55by sliding along the length direction of the second path regulatingmember 50. By coupling the first coupling portions 55 and the secondcoupling portions 56 to each other, the receiving portion 53 and the lidportion 54 are held so as not to separate from each other.

Composition of Filler 60

As shown in FIG. 4 , the wire harness 10 includes a filler 60 providedbetween the cover portion 52 and the wire harness body 11. The filler 60is injected into the inner circumferential side of the cover portion 52through a through hole 58 provided in the lid portion 54. The throughhole 58 is a hole passing through the cover portion 52 from the outercircumferential side to the inner circumferential side. The through hole58 passes through the cover portion 54 along the diameter direction ofthe lid portion 52, for example. The through hole 58 is an elongatedhole that is elongated in the length direction of the wire harness body11, for example. The through hole 58 is provided at a position thatcorresponds to the insertion opening 40X of the first path regulatingmember 40. In other words, the through hole 58 faces the insertionopening 40X in the diameter direction of the cover portion 52.

The filler 60 is made of a resin material. Examples of the resinmaterial used for the filler 60 include ethylene copolymers such as EEA(ethylene ethyl acrylate copolymer) and EVA (ethylene vinyl acetatecopolymer), and silicone materials such as a single-liquid type ofliquid silicone rubber. For example, if the filler 60 is anethylene-based copolymer, it is possible to inject the filler 60 throughthe through hole 58 using a glue gun. When injecting the filler 60, themelted filler 60 is first injected through the through hole 58 into thespace circumferentially inward of the cover portion 52. The filler 60flows into the space between the exterior member 30 and the coverportion 52 inward of the insertion opening 40X of the first pathregulating member 40. Note that the viscosity of the filler 60 and theinjection pressure are set such that the filler 60 does not spreadentirely around the spaces corresponding to the small diameter portions32 of the exterior member 30. As a result, the space between theexterior member 30 and the cover portion 52 inward of the insertionopening 40X is appropriately filled with the filler 60.

After being injected into the space between the exterior member 30 andthe cover portion 52, the filler 60 is allowed to solidify. In thesolidified state, the filler 60 has a first section 61 located in thespace between the exterior member 30 and the cover portion 52 inward ofthe insertion opening 40X. The first section 61 adheres to the innercircumferential surface of the cover portion 52, the outercircumferential surface of the exterior member 30, and the first endportion 41 and the second end portion 42 of the first path regulatingmember 40.

The wire harness body 11, which includes the exterior member 30 and thefirst path regulating member 40, is pressed against the innercircumferential surface of the cover portion 52 by the pressure of thefirst section 61 of the filler 60. Note that the filler 60 preferablyhas an appropriate extent of elasticity in the solidified state.

Also, in the solidified state, the filler 60 has a second section 62that is formed in the through hole 58. The second section 62 adheres tothe inner circumferential surface of the through hole 58. The secondsection 62 closes the through hole 58, for example.

As shown in FIG. 2 , the wire harness 10 includes a first slideregulating member 71 that regulates sliding movement of the first pathregulating member 40 in the length direction of the exterior member 30,for example. The wire harness 10 also includes a second slide regulatingmember 72 that regulates sliding movement of the second path regulatingmember 50 in the length direction of the exterior member 30, forexample. The first slide regulating member 71 and the second slideregulating member 72 can be a binding band made of resin or metal, acrimping ring, adhesive tape, or the like. The first slide regulatingmember 71 and the second slide regulating member 72 of the presentembodiment are pieces of adhesive tape. The first slide regulatingmember 71 is wrapped around the exterior member 30 and the end portionof the first path regulating member 40 that is not coupled to the secondpath regulating member 50. The second slide regulating member 72 iswrapped around the exterior member 30 and the end portion of the secondpath regulating member 50 that is not coupled to the first pathregulating member 40.

The following describes effects of the present embodiment.

(1) The wire harness 10 includes the filler 60 that is introduced intothe space between the wire harness body 11 and the cover portion 52through the through hole 58. According to this configuration, theportion of the wire harness body 11 that passes through the coverportion 52 is pressed against the cover portion 52 by the filler 60.This makes it possible to suppress rattling between the cover portion 52and the wire harness body 11. Note that in the above embodiment, thepressure of the filler 60 pushes the receiving portion 53 and the lidportion 54 so as to spread away from each other. This thereforesuppresses rattling between the first coupling portions 55 of thereceiving portion 53 and the grooves 57 of the lid portion 54.

(2) The first section 61 of the filler 60 is formed in the insertionopening 40X. The first section 61 is interposed between the outercircumferential surface of the exterior member 30 and the innercircumferential surface of the cover portion 52. According to thisconfiguration, the exterior member 30 and the first path regulatingmember 40 can be pressed against the cover portion 52 by the filler 60introduced into the space between the exterior member 30 and the coverportion 52. Also, due to the filler 60 being provided in the insertionopening 40X of the first path regulating member 40, rotation of thefirst path regulating member 40 in the circumferential direction can besuppressed by the filler 60. Moreover, due to the filler 60 being formedin the insertion opening 40X of the first path regulating member 40, thecover portion 52 can have a smaller size in the diameter direction thanin the case of a configuration in which the filler 60 is provided so asto be in contact with the outer circumferential surface of the firstpath regulating member 40.

(3) The through hole 58 faces the insertion opening 40X in the diameterdirection of the cover portion 52. According to this configuration, thefiller 60 can be favorably introduced into the insertion opening 40X.

(4) The second section 62, which is a portion of the filler 60, isformed in the through hole 58. According this configuration, the throughhole 58 can be closed by the filler 60.

(5) The second path regulating member 50 includes the body portion 51that regulates the path of the exterior member 30, and the receivingportion 53 provided at a lengthwise end of the body portion 51 of thewire harness body 11. Also, the second path regulating member 50includes the lid portion 54 that, together with the receiving portion53, covers the entire circumferential range of the first path regulatingmember 40. The receiving portion 53 and the lid portion 54 constitutethe cover portion 52. According to this configuration, it is possible toconfigure the cover portion 52 that, with use of the receiving portion53 and the lid portion 54, covers the outer circumferential surface ofthe first path regulating member 40.

(6) The through hole 58 is provided in the lid portion 54. According tothis configuration, the filler 60 can be introduced through the throughhole 58 provided in the lid portion 54.

(7) The filler 60 is made of a resin material. According to thisconfiguration, the wire harness body 11 can be favorably pressed againstthe cover portion 52 by the filler 60 made of a resin material.

(8) The attachment member (attachment) for attachment to the first pathregulating member 40 is the second path regulating member 50 that isattached to the outer circumferential surface of the exterior member 30and regulates the path of the exterior member 30. Also, the coverportion 52 is provided at a lengthwise end portion of the second pathregulating member 50, and covers the outer circumferential surface of alengthwise end portion of the first path regulating member 40. For thisreason, the first path regulating member 40 and the second pathregulating member 50 are coupled in the length direction. Accordingly,the path of the exterior member 30 is regulated with continuity by thefirst path regulating member 40 and the second path regulating member50.

(9) The first path regulating member 40 regulates the path of thestraight portion 11A, which is a straight portion in the path of thewire harness body 11. The second path regulating member 50 regulates thepath of the bent portion 11B, which is a portion that bends along thepath of the wire harness body 11. According to this configuration,deviation of the path of the straight portion 11A and the path of thebent portion 11B of the wire harness body 11 from the respective desiredpaths is suppressed with continuity.

The present embodiment can be implemented with modifications such as thefollowing. The present embodiment and the following modified examplescan be implemented in combination with each other as long as notechnical contradiction arises.

In the cover portion 52 of the above-described embodiment, the throughhole 58 for introduction of the filler 60 is provided in the lid portion54, but the present disclosure is not particularly limited to this.

For example, as shown in FIG. 5 , a through hole 81 for introduction ofthe filler 60 may be provided in the receiving portion 53 of the coverportion 52. As shown in this figure, the through hole 81 is a hole thatpasses through the cover portion 52 from the outer circumferential sideto the inner circumferential side.

The through hole 81 is provided at a positioncorresponding to the outer circumferential surface of the connectingportion 43 of the first path regulating member 40. In other words, thethrough hole 81 faces the outer circumferential surface of theconnecting portion 43 in the diameter direction of the cover portion 52.The filler 60 introduced through the through hole 81 is interposedbetween the outer circumferential surface of the connecting portion 43and the inner circumferential surface of the receiving portion 53. Evenwith this configuration, the first path regulating member 40 can bepressed against the cover portion 52 by the filler 60 introduced intothe space between the connecting portion 43 of the first path regulatingmember 40 and the cover portion 52.

Although the cover portion 52 has a configuration including thereceiving portion 53 and the lid portion 54 in the above-describedembodiment, the present disclosure is not limited to this, and the coverportion 52 may be changed to a configuration having a tubular shape andnot capable of disassembly or deformation.

Also, although the lid portion 54 in the above embodiment is a memberseparate from the receiving portion 53, the present disclosure is notparticularly limited to this, and the lid portion 54 may be integratedwith the receiving portion 53.

For example, in the configuration shown in FIG. 6 , the lid portion 54is integrated with the receiving portion 53 via a thin hinge portion 91.In other words, the receiving portion 53 and the lid portion 54 areconnected by the hinge portion 91. The hinge portion 91 connects onecircumferential end of the receiving portion 53 and one circumferentialend of the lid portion 54. A lock portion 92 is provided at the othercircumferential end of the receiving portion 53. A claw portion 93 isprovided at the other circumferential end of the lid portion 54.

The lid portion 54 can pivot around the hinge portion 91 between an openposition and a closed position, which is shown in FIG. 6 . The clawportion 93 is hooked on the lock portion 92 when the lid portion 54 isat the closed position. As a result, the lid portion 54 is held at theclosed position. In this way, the receiving portion 53 and the lidportion 54 are coupled to each other. In the state in which thereceiving portion 53 and the lid portion 54 are coupled, the coverportion 52 has an annular shape that surrounds the outer circumferencesof the end portions of both the exterior member 30 and the first pathregulating member 40. Even when the cover portion 52 has theconfiguration shown in FIG. 6 , rattling between the cover portion 52and the wire harness body 11 can be suppressed by pressure applied bythe filler 60.

In the cover portion 52 of the above-described embodiment, theprotruding-receding relationship between the first coupling portions 55and the second coupling portions 56 may be reversed. In other words, thesecond coupling portions 56 may be inserted into grooves provided in thefirst coupling portions 55.
